Answer:
2.26 meters
Step-by-step explanation:
so the volume for a cylinder is
v= π r² x h
now just substitute in the numbers you know:
180= π r² x 11.25
now rearrange the formula:
180= r² x 11.25π
(rearranging allows you to do this next bit with ease)
now divide by 11.25π on both sides to get
[tex]\frac{180}{11.25\pi }[/tex]= r²
to maintain accuracy, don't divide yet
now you know what r² is but you want r, so square root it:
[tex]\sqrt{\frac{180}{11.25\pi } }[/tex]=r
type that into a calculator and i think the answer is ...
2.25675833419
write the long answer in case you make a mistake when rounding
round appropriately : 2.26 meters ( I've done it to 2 decimal places)
and hopefully that's the correct answer.
Claire can eat 3/4 of a pizza every 5 minutes. How much of a pizza can she eat in 1 minute?
Answer:
3/20 of the pizza
Step-by-step explanation:
To find how much she eats in one minute, you have to change the fraction into a decimal, which is 0.75, and divide that by 5. Once you've done that, you get 0.15 of the pizza in a minute. this can be simplified into the fraction 3/20.
Answer:
3/20
Step-by-step explanation:
If she can do 3/4 per 5 minutes, the amount in 1 minute is 1 fifth of 3/4, so multiply 3/4 by 1/5 to get 3/20.

The statements about the box plot in Figure A2 are analyzed and determined to be true or false.
Explanation:The graph in Figure A2 is a box plot. Let's go through each statement and determine if it is true or false.
A. Twenty-five percent of the data are at most five: True. The box extends from the first quartile (Q1) to the third quartile (Q3), which represents the middle 50% of the data. The line inside the box is the median, and the whiskers extend to the minimum and maximum values. In this case, the box goes up to five, indicating that 25% of the data are at most five.
B. There is the same amount of data from 4-5 as there is from 5-7: False. The box plot shows the range of values within the quartiles. In this case, the range from 4-5 is smaller than the range from 5-7, indicating that there is more data in the latter range.
C. There are no data values of three: True. The box plot does not have any outlier points at the value of three, indicating that there are no data values at that point.
D. Fifty percent of the data are four: False. The median value in the box plot is the value that divides the data into two equal halves. In this case, the median is not at four, so 50% of the data are not equal to four.

A can contains 40 chips: 10 each of read and blue, 12 pink, and the remaining black.If Susan were to remove 3 black and 2 red chips, what is the probability that next one she removes is black? Please Help!
Answer:
1:7
Step-by-step explanation:
R = RED | B = BLUE | P = PINK | BL = BLACK | c = chips
10R + 10B + 12P = 32 chips
40c - 32c = 8 black chips
8BL - 3BL = 5 black chips
10R - 2R = 8 red chips
2R + 3BL = 5 chips
40c - 5c = 35 chips
5BL : 35c = 1:7
The probability that next one Susan removes is black chips is 1/7.
What is probability?
The probability is defined as the possibility of an event is equal to the ratio of the number of outcomes and the total number of outcomes.
Total no. of chips = 40
No. of red chips = 10
No. of blue chips = 10
No. of pink chips = 12
No. of black chips = 8
If Susan were to remove 3 black and 2 red chips
So, No. of available black chips = 8 -3 = 5
No. of available red chips = 10 - 2 = 8
Total removed chips = 5
Total no. available of chips = 35
The probability that next one Susan removes is black chips = 5/35 = 1/7
Hence, the probability that next one Susan removes is black chips is 1/7.

Which equation is true?
9x2 – 25 = (3x - 5)(3x – 5)
9x2 – 25 = (3x – 5)(3x + 5)
9x2 – 25 = -(3x + 5)(3x + 5)
9x2 - 25 = -(3x + 5)(3x - 5)
Answer:
9x2 – 25 = (3x – 5)(3x + 5)
Step-by-step explanation:
(3x – 5)(3x + 5)
= 9x² + 15x - 15x - 25
= 9x² - 25
Final answer:
The correct equation is 9x² – 25 = (3x – 5)(3x + 5), as it is the factored form of the difference of squares, where 9x² is the square of 3x and 25 is the square of 5.
Explanation:
The equation we are considering is 9x² – 25. We need to determine which of the provided options is a true equality. The equation 9x² – 25 is a difference of squares, which factors as (a² – b²) = (a – b)(a + b). In this case, a is 3x and b is 5 because (3x)² = 9x² and 5² = 25.
Thus, the factored form of the equation 9x² – 25 is (3x – 5)(3x + 5). So, the correct equation from the given options is 9x² – 25 = (3x – 5)(3x + 5).

The length ends between the
centimeter-mark.
Answer:
It ends between 13cm and 14cm mark.
Step-by-step explanation:
Since this marker in question is almost 14 centimeters long and definitely ends between two centimeter marks, the two centimeters that the length of this marker ends between on a ruler should be the 13cm and 14cm marks on the ruler.
Final answer:
The length of a marker almost 14 centimeters long ends between the 13 centimeter-mark and the 14 centimeter-mark on a ruler.
Explanation:
When measuring a marker that is almost 14 centimeters long, we look at the ruler and identify the two consecutive centimeter marks between which the length of the marker falls. If the marker is almost 14 centimeters long, this means it is greater than 13 centimeters but less than 14 centimeters.
Therefore, we can confidently say that the marker's length lies between the 13 centimeter-mark and the 14 centimeter-mark on the ruler. The smaller centimeter-mark would be 13, as it is the immediately preceding whole centimeter before the marker ends.

Given that r varies inversely as t , then the equation relating them is
r = [tex]\frac{k}{t}[/tex] ← k is the constant of variation
To find k use the condition t = - 6 when r = - 2, then
- 2 = [tex]\frac{k}{-6}[/tex] ( multiply both sides by - 6 )
12 = k, thus
r = [tex]\frac{12}{t}[/tex] ← equation of variation

Plot the values that represent the minimum, maximum, first quartile, median, and third quartile of the number of people waiting in line.
Plz help i have alot of trouble finding the quartials
The minimum value is 19, maximum is 37, median is 28.5, first quartile is 23.5, and third quartile is 33.5. These measures are calculated by organizing the data in ascending order and finding the middle and approximated middle values of the data set and its halves.
Explanation:First, let's arrange your data in ascending order: 19,20,21,22,23,24,26,27,28,29,30,31,32,33,34,35,36,37. There are 18 data points here.
The minimum value is 19 and the maximum value is 37.
To calculate the median (the middle number), since we have an even number of data points, we take the average of the 9th and 10th numbers. (28+29)/2 = 28.5.
Now, to find the first quartile (lower median), we look at the median of the lower half of the data (excluding the overall median if it's part of the data). The lower half of the data is: 19,20,21,22,23,24,26,27,28. So, we take the average of 23 and 24 which is 23.5.
For the third quartile (upper median), we look at the median of the upper half of the data. Here it is: 29,30,31,32,33,34,35,36,37. So, we take the average of 33 and 34 which is 33.5.

2
+8x+15x, squared, plus, 8, x, plus, 15 square meters and a width of x+3x+3x, plus, 3 meters.
What expression represents the length of the rectangle?
Answer:
The length of the rectangle is x+5.
Step-by-step explanation:
Given : The rectangle below has an area of [tex]x^2+8x+15[/tex] square meter and a width of [tex]x+3[/tex] meter.
To find : What expression represents the length of the rectangle?
Solution :
The area of the rectangle is given by,
[tex]\text{Area}=\text{Length}\times \text{Breadth}[/tex]
[tex]\text{Area}=x^2+8x+15[/tex]
[tex]\text{Breadth}=x+3[/tex]
[tex]x^2+8x+15=\text{Length}\times(x+3)[/tex]
[tex]\text{Length}=\frac{x^2+8x+15}{x+3}[/tex]
[tex]\text{Length}=\frac{(x+5)(x+3)}{x+3}[/tex]
[tex]\text{Length}=x+5[/tex]
Therefore, the length of the rectangle is x+5.
Final answer:
The length of the rectangle is found by dividing the area (x² + 8x + 15) by the width (x + 3), which simplifies to x + 5 meters, as the (x + 3) factor cancels out.
Explanation:
To find the length of the rectangle, we can use the area formula for rectangles, which is area = length × width.
According to the question, the area of the rectangle is given by the quadratic expression x² + 8x + 15, and the width is given by x + 3. To find the length, we divide the area by the width:
length = ²/(x + 3)
² + 8x + 15 is factorable, and its factors are (x + 5)(x + 3), which simplifies to:
length = (x + 5)(x + 3)/(x + 3)
When the polynomial is factored, we can see that the (x + 3) terms cancel each other out:
length = x + 5
